Objective: Traumatic dental injuries (TDIs) require immediate emergency care. Nondental healthcare professionals frequently encounter these cases, yet studies indicate their knowledge of emergency management is often insufficient. The ToothSOS mobile application, launched by the International Association of Dental Traumatology, provides first-aid guidance on dental trauma. This is the first study in Saudi Arabia to assess medical, nursing, and pharmacy students’ knowledge of TDIs and awareness of the ToothSOS app, identifying key gaps and opportunities for integration into curricula. Methods: A cross-sectional study was conducted among 361 medical, nursing, and pharmacy students at King Abdulaziz University (KAU) using a validated electronic questionnaire. The survey collected demographic data, assessed knowledge of TDIs, and evaluated awareness of the ToothSOS app. Sufficient knowledge was defined as correctly answering at least five of eight knowledge-based questions. Descriptive statistics, chi-square tests, and logistic regression were used for analysis. Results: Only 26% of participants demonstrated sufficient knowledge. Nursing students scored significantly higher than medical and pharmacy students ( p < .05). Female students were three times more likely to have adequate knowledge ( p < .001). Awareness of the ToothSOS app was low (21.1%), but 78.4% of unaware participants expressed willingness to use it. Conclusion: Healthcare students at KAU showed inadequate knowledge of TDIs and limited awareness of the ToothSOS app. Integration of TDI management training into healthcare curricula is recommended. Promoting the ToothSOS app as an accessible resource can enhance the emergency management of TDIs.

Background/Objectives: Orthodontic retention is a critical phase of treatment aimed at maintaining teeth in corrected positions and preventing relapse, which may occur in up to 70% of cases. Successful retention depends on both orthodontists’ application of effective strategies and patient compliance in retainer use and maintenance. While previous studies have focused on orthodontists’ retention protocols, less is known about patients’ knowledge and expectations. This study assessed knowledge and expectations of orthodontic retention among individuals seeking orthodontic treatment in Saudi Arabia. Methods: A cross-sectional survey was conducted at the orthodontic clinics of King Abdulaziz University, Faculty of Dentistry, Jeddah, Saudi Arabia. Patients on the waiting list who had not yet begun treatment were invited to participate; guardians completed surveys for minors. Data were collected using a validated, culturally adapted questionnaire and analyzed with descriptive statistics and multivariable logistic regression. Results: Of 243 patients contacted, 161 responded (66.3%). While 62.1% were aware of retention appliances, only 31.1% believed they were always required. Overall, 57.1% expected retention to last 1–3 years and were divided between bonded and removable retainers. Orthodontists were the most trusted information source, while social media was least trusted. Family history and higher education were associated with greater awareness and support for lifelong retention, though most associations were not significant after multiple-testing correction. Conclusions: Despite awareness of retention appliances, misconceptions persist. Family history, education, and age influenced perceptions, underscoring the need for tailored education and guidance toward reliable orthodontic information sources.
